In the evening of 11/22/2016, Tepco announced the radiation monitoring post in the sea has been suspended due to the quake. The post is situated at the end of the breakwater of Fukushima plant port. They cannot monitor the radioactive substance spreading to the Pacific with this monitoring post out of order.

They also admitted the underwater fence was damaged, and also the coolant water got out of the common spent fuel pool due to the quake. It reportedly spread over 2m * 3m but the exact volume is not announced.


About 40 minutes after the quake, Tepco announced they found no abnormality in Fukushima plant however 1m high tsunami was observed reaching the plant port.

Dans la soirée du 22 novembre 2016, Tepco a déclaré que la borne de surveillance de la radioactivité située en mer a été arrêtée à cause du séisme. Cette borne est située au bout de la jetée du port de la centrale de Fukushima. Ils ne peuvent plus surveiller la radioactivité qui se répand dans le Pacifique avec cette borne en panne.

Ils ont aussi reconnu qu’à cause du séisme la barrière souterraine était endommagée et également que du liquide de refroidissement s’était échappé de la piscine commune à assemblages usagés. Il aurait fuit sur plus de 2 * 3 m mais le volume exact n’est pas communiqué.

Tepco a déclaré ne pas avoir relevé d’anomalie dans la centrale de Fukushima environ 40 minutes après le séisme, alors qu’un tsunami de 1 m de haut était observé atteignant le port de la centrale.

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
